SPECIFICATION forming part of Letters Patent No. 634,228, dated October 3, 1899.

Application filed April 91 1 39 9 To all whom it may concern: Be it known that we, CHARLES E. BARRETT and JOHN H. HORNE, of Lawrence, county of In certain kinds of pulp, notably the wood pulp which is now largely used in making paper, the water drains away very rapidly,

so that the pulp may become nearly dry before it leaves the shake-frame, and thus not be properly laid when it reaches the rollers. This tendency may be obviated to a considerable extent by downwardly inclining the shake-frame toward the rollers, so thatthe water tends to travel along with the pulp and will not, therefore, drain out through the wire so rapidly. It is furtherdesirable that the amount of inclination orslope should be variable, so as to adapt the machine for pulp of different kinds or grades.

It is the object of this invention ,to accomplish these purposes, and in accordance therewith the shake-frame is' mounted on a movable support or frame, the end of which where the pulp is received being arranged to be raised or lowered, so that the said shake-frame can be inclined at any angle to the permanent rails, or, if desired, retained level. The ends of the shake-rails where they adjoin the stationary support are so arranged that they are not raised or lowered in the adjustment of this part of the machine, the adjusting movement having this point as an axis. As herein shown, the stationary rails and the shake rails are both supported adjacent to each other upon an upright at the end of the adjustable staging, the stationary rails being so arranged that said upright is capable of a slight pivotal movement with relation to said rails, so that as the staging is raised the stationary Serial No. 713,567. (No model.)

I rails willnot be strained and will always re main at the same level with the pivoted ends of the shake-rails.

Figure 1 is a side elevation of a portion of a Fourdrinier paper-machine, showing the shake-rails and sufficient of the stationary rails to illustrate the relation between said parts; and Fig. 2 is "an end elevation of the same, the floor or main supporting portion of the room in which the machine is placed being shown in section in both figures.

That portion of the machine which comprises the shake-rails A, the deckle-strap B, the table-rolls O, and the wire D, all of which parts are of usual construction, is mounted, in accordance with the present invention, upon a movable frame or support, herein shown as comprising longitudinal beams a and transverse beams b, the former constituting the main support for the machine elementsabovenamed. Thesaidframeisshown as provided at one end with vertical members or supports a to which the shake-rails A are ported at the opposite end upon rolling supports A substantially as shown and described in Patent No. 595,753, granted December 22, 1897, to Charles E. Barrett. In this instance, however, the said rolling supports instead of resting on the floor rest upon the beams a of the movable frame or support for this part of the machine. Since the shake-frame carries the breast-roll, the table-rolls, 850., it is ob- Vious that the inclination or slope of this part of the machine, including the wire, will be varied by raising or lowering the end of the frame or support a I). Since the wire extends directly from this part of the machine to the part where the stationary rails E are supported, it is essential that the end of the shake-rails should be adjacent to the ends of the permanent rails, and, as herein shown, the permanent rails rest upon the uprights a being loosely connected therewith and beveled at E so that the said post can be rocked with relation to said fixed rails without straining the same. This part therefore constitutes the axis upon which the whole frame is moved when the opposite end thereof is lifted or lowered, and to accommodate such movepivoted at A the said shake-rails being supment the frame is shown as provided with wheels or other antifriction devices a resting upon a pillar orsupport a, which is preferably below the floor of the room in which the machine is placed, in order that the upper portion of the frame a may be substantially on a level with the said floor. lVhen, therefore, the farther end of the frame is lifted or lowered, the wheel a will travel along the surface of the post a the shake-rails and the permanent rails remaining in the same position with relation to each other.

The end of the frame a may be raised or lowered by any suitable means, it being desirable, however, to arrange a compensating gear, since the frame is exceedingly heavy, while the distance through which it is to be moved is relatively small. As herein shown, the said frame is supported upon cams c, the beams a being provided with wheels a or other suitable antifriction devices resting on the said cams, one of which is below each side beam. These cams are shown as secured upon a shaft 0 provided with bearings 0 supported upon pillars 0 corresponding to the pillars a and preferably below the surface of the floor F. To operate the cams, the shaft 0 is shown as provided with a gearwheel 0 cooperating with a worm d, which is shown as mounted on a vertical shaft (1 provided with an actuating-wheel (F. The said shaft is mounted in a suitable bearing upon the floor F, so that the wheel (i will be in a convenient position to be actuated by the attendant. To raise the end of the frame a b, therefore, in order to produce the desired inclination or slant of the wire part, it is only necessary to turn the wheel (Z and thus cause the rotation of the shaft 0 so that the cams turn, thereby gradually lifting the entire frame at this end until it has reached the desired position. The nature of the gearing is such that no locking devices are necessary, it being obvious that the frame will be supported in any desired position until changed by turning the wheel d e claim- 1. A movable staging or support for the shake-frame of the paper-machine and means for changing the vertical position of the breastroll end of said support without changing the vertical position of the opposite end thereof, to thereby vary the inclination of the wire upon the shake-frame, as set forth.

2. A movable staging or support for the shake-frame of a paper-machine, said staging being independent of the support for the remainder of the machine, one portion of said staging also constituting a support for the stationary rails; and means for vertically adjusting the position of the breast-roll end of said staging without varying the vertical position of that part which constitutes the support for the stationary rails, as set forth.

3. A movable staging or support for the shake-frame of a paper-machine, said staging being provided at one end with vertical members to which the shake-rails are pivoted, (said vertical members also constituting supports for the stationary rails) and at the other end with a vertical support for the breastroll; rolling-supports for said staging below the vertical members at the stationary rail end of the staging; and vertically-adjustable members to support said staging near the breast-roll end thereof, as set forth.

4. A movable staging or support for the shake-frame of a paper-machine one or more cams upon which said staging rests at the breast-roll end; and means for rotating the said cams to vary the vertical position of said breast-roll end of the staging, the other end being arranged to maintain the same vertical position, as set forth.

5. A movable staging or support for the shake-frame of a paper-machine, one or more cams upon which the breast-roll end of the said staging rests, a gear-wheel connected with said cams and adapted to rotate the same, and a worm cooperating with said gear to vary the vertical position of the breast-roll end only of said staging, substantially as and for the purpose described.

6. A movable staging or support for the shake-frame of a paper machine, the breastroll end of which said staging is adapted to be raised or lowered to vary the angle of the wire support along the shake-frame to the said wire support beyond the said shakeframe, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
